Hello,
I don't know about Eizo s-pva but I have seen several times a LaCie 324 (which also an s-pva) of a friend and what upset me a lot was shadow detail. I detailed this issue in a precedent post (
link). This lead me to buy a Nec 2690 which is h-ips a-tw. From an amateur point of view, I am really happy with this Nec monitor.
John.
